Which sequence of events is required to form a limestone cave where you can walk around and observe cave formations, such as stalactites?
A) limestone is below the water table, then lowering of the water table, then water dripping from the ceiling
B) lowering of the water table, then water dripping from the ceiling, then limestone is below the water table
C) water dripping from the ceiling, then lowering of the water table, then limestone is below the water table
D) none of these
Limestone Cave
A natural underground space formed by the dissolution of limestone by acidic water, often featuring stalactites and stalagmites.
Water Table
The surface between the unsaturated zone and the saturated zone, as in the top of groundwater in an unconfined aquifer.
Stalactites
Icicle-shaped formations that hang from the ceilings of caves, formed by the deposit of minerals from dripping water.

Final Answer :
A
Explanation :
Limestone caves form when limestone is initially below the water table, allowing water to dissolve the limestone and create cavities. The lowering of the water table then exposes these cavities, and water dripping from the ceiling afterward can deposit minerals to form stalactites and other cave formations.
